In coronary artery bypass surgery, end-to-side anastomosis is commonly used; however, excessive tightening during suturing can cause stenosis. This study utilizes CFD technology to compare various stenosis models and analyze the impact of stenosis severity on blood flow.
The image illustrates wall shear stress (WSS).
